Nrog rau kev sib sib zog nqus ntawm kev hloov kho thiab qhib, Tuam Tshoj tau ua tiav cov txheej txheem xaim kos duab tuag thiab cov khoom siv tuag qhov ntsuas cov cuab yeej tsim los ntawm cov teb chaws industrialized. Kev tshuaj xyuas qhov tuag qhov qauv ntawm txawv teb chaws hlau kos duab tuag tau muab peb kev pom rau hauv cov tswv yim tsim ntawm niaj hnub hlau kos duab tuag, muab ib qho kev siv rau kev txhim kho cov qauv tsim ntawm hlau kos duab tuag hauv Suav teb.
Cov qauv ntawm cov hlau kos duab tuag core tuaj yeem muab faib ua tsib ntu raws li nws txoj haujlwm ua haujlwm: thaj chaw nkag, thaj chaw lubrication, thaj chaw ua haujlwm, thaj chaw loj, thiab thaj chaw tawm. Lub puab txoj kab uas hla ntawm cov hlau kos duab tuag yog ib qho tseem ceeb heev, vim nws txiav txim siab lub tensile quab yuam yuav tsum tau rau compress cov hlau thiab cuam tshuam cov residual kev nyuaj siab nyob rau hauv lub kos hlau. Lub luag haujlwm ntawm txhua ntu ntawm cov tub ntxhais tuag yog raws li hauv qab no: thaj chaw nkag tau yooj yim rau kev xaim xov thiab tiv thaiv cov hlau los ntawm khawb qhov tuag los ntawm kev nkag; lub lubrication cheeb tsam pab txhawb cov kev taw qhia ntawm lubricant rau hauv cov hlau; thaj chaw ua haujlwm yog qhov tseem ceeb ntawm qhov tuag qhov, qhov twg cov txheej txheem deformation ntawm cov hlau yuav tshwm sim, txo tus ntoo khaub lig thawj -section mus rau qhov yuav tsum tau hla -sectional loj.
Thaum kos duab conical hlau, qhov chaw nyob ntawm qhov ntim ntawm cov hlau nyob rau hauv qhov chaw ua haujlwm yog ib qho frustum, uas yog hu ua deformation zone. Lub khob hliav qab ib nrab-lub kaum sab xis (tseem hu ua qhov tuag qhov ib nrab- lub kaum sab xis) hauv thaj chaw ua haujlwm feem ntau yog siv los txiav txim siab qhov loj ntawm qhov kos duab; thaj tsam sizing yog siv kom tau qhov tseeb qhov loj ntawm cov hlau kos hlau; qhov chaw tawm yog siv los tiv thaiv cov hlau hlau los ntawm khawb vim qhov tsis sib xws.
